World number one Iga Swiatek won the Tracy Austin Group in style with a comprehensive straight-sets victory over Coco Gauff in the WTA Finals in Fort Worth on Saturday.

Swiatek made it three wins out of three matches in the group stage without dropping a set, getting past fourth seed Gauff 6-3 6-0 in one hour and 10 minutes.

The 2022 US Open and French Open champion advances and will take on seventh seed Aryna Sabalenka in the WTA Finals semi-finals on Sunday.

The Pole made light work of Gauff, improving her head-to-head dominance to 5-0, with her 28-minute second set representing the 22nd bagel she has doled out this season.

Swiatek committed 15 unforced errors in the first set, but made only two in a lopsided second frame where she won 26 of 36 points.

Gauff had pushed Swiatek to 3-3 in the first set, before the top seed broke her twice to clinch the opening frame, putting her foot to the throat in the second.
